Description
Technical field
This utility model relates to micromotor correlative technology field, refers in particular to the commutator assembly of a kind of micromotor.
Background technology
As a kind of micromachine, small vibration motor is mainly used in the miniature electrics such as mobile phone, beeper, electronic toy
On product.As the daily carry-on instrument of people or amusement article, the convenience of the assembling of small-sized electronic product, high-quality, low one-tenth
This, the aspect such as operation convenience is science and technology Research Emphasis.
Commutator components belongs to the critical component of rotary part in small vibration motor product, its molding difficulty, difficult processing
Degree, the control of quality stability, all manufactures to small vibration motor such as energy-saving and cost-reducing produce considerable influence.
Diverter is as one of requisite vitals of micro-burst motor, conventional metals part retaining collar and metal
When part axle is assembled into rotating assembly, retaining collar problem of Cracking easily occurs and pulling-out force concordance is irregular asks because tolerance issues causes
Topic.Therefore, develop a kind of new diverter pivot structure and ensure product quality and promote yield rate, reduce waste and become each producer
Problem.
Utility model content
This utility model is to there is above-mentioned deficiency in prior art to overcome, it is provided that a kind of product quality is high and becomes
The commutator assembly of the micromotor that product rate is high.
To achieve these goals, this utility model is by the following technical solutions:
The commutator assembly of a kind of micromotor, including rotating shaft, working of plastics and brush, described rotating shaft and brush are placed in be moulded
On materials and parts, described rotating shaft, working of plastics and brush uses the mode of injection mo(u)lding to be made, and described rotating shaft includes fixing head
And axis body, described rotating shaft is integrated.
The fixing head of rotating shaft and axis body use integrated mode to be made, it is not necessary to by independent to fixing head and axis body
Making and again carry out machining and form it into rotating shaft, so there is not fixing head problem of Cracking, the most not existing because of fixing
Head and axis body between tolerance issues and cause the irregular problem of pulling-out force concordance, by rotating shaft, working of plastics and brush use injection
The mode of molding makes and becomes commutator assembly, saves assembling labour force, easily realizes automated production simultaneously, it is ensured that produce
The quality of product, improves the yield rate of product.
As preferably, the fixing head diameter of described rotating shaft is more than the axis body diameter of rotating shaft, and described fixing head is placed in axis body
One end, the shape of cross section of described rotating shaft is T-shaped, and described axis body is provided with one end of fixing head and is placed in the inside of working of plastics.Logical
Cross the structure design of rotating shaft so that rotating shaft can preferably be positioned in working of plastics, prevent rotating shaft from departing from working of plastics and causing changing
Damage to device assembly.
As preferably, the lateral surface of described fixing head is provided with hole, some equally distributed location.The design of fixing head, it is possible to
Prevent rotating shaft from dallying in working of plastics and working of plastics cannot be driven to rotate, so that rotating shaft is preferably positioned in working of plastics,
Ensure that the concordance of pulling-out force in use.
Preferred as another kind, the lateral surface of described fixing head is provided with some equally distributed positioning convex.Fixing head
Design, it is possible to prevent rotating shaft from dallying in working of plastics and working of plastics cannot be driven to rotate, so that rotating shaft is preferably positioned at
In working of plastics, it is ensured that the concordance of pulling-out force in use.
The beneficial effects of the utility model are: save assembling labour force, easily realize automated production, it is ensured that product
Quality, improve the yield rate of product, decrease the waste of material, improve firmly may be used between rotating shaft and working of plastics simultaneously
By property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of rotating shaft.
In figure: 1. rotating shaft, 2. working of plastics, 3. brush, 4. fixing head, 5. axis body.
Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
In embodiment described as shown in Figure 1, Figure 2, the commutator assembly of a kind of micromotor, including rotating shaft 1, working of plastics 2 and
Brush 3, rotating shaft 1 and brush 3 are placed on working of plastics 2, rotating shaft 1, working of plastics 2 and brush 3 use the mode of injection mo(u)lding to make and
Becoming, rotating shaft 1 includes fixing head 4 and axis body 5, and rotating shaft 1 is integrated.
Fixing head 4 diameter of rotating shaft 1 is more than axis body 5 diameter of rotating shaft 1, and fixing head 4 is placed in one end of axis body 5, rotating shaft 1
Shape of cross section is T-shaped, and axis body 5 is provided with one end of fixing head 4 and is placed in the inside of working of plastics 2.If the lateral surface of fixing head 4 is provided with
Dry hole, equally distributed location, the shape of cross section in hole, location can be V-type, T-shaped etc..In addition to Design Orientation hole, fixing
The lateral surface of 4 is also provided with some equally distributed positioning convex, and the shape of positioning convex can be cylindrical, circular cone
Shape, square etc..
When making, first use integrated mode to be made fixing head 4 and the axis body 5 of rotating shaft 1, so set
Meter avoids the need for that fixing head 4 and axis body 5 are fabricated separately and again carry out machining and forms it into rotating shaft 1, so not depositing
At fixing head 4 problem of Cracking, the most do not exist and cause pulling-out force concordance not because of the tolerance issues between fixing head 4 and axis body 5
Even problem；Then use the mode of injection mo(u)lding to make rotating shaft 1, working of plastics 2 and brush 3 to become commutator assembly, so set
Meter can save assembling labour force, easily realizes automated production, it is ensured that the quality of product, the yield rate of improving product simultaneously.
